Says the company's Dan O'Sullivan, "Taken together, the significance of these exposed buckets is hard to overstate. In the hands of competent threat actors, these cloud servers, accessible to anyone stumbling across their URLs, could have exposed both Accenture and its thousands of top-flight corporate customers to malicious attacks that could have done an untold amount of financial damage."

Accenture secured the databases the day after UpGuard notified it of the exposure.

SecureWorld has reached out to Accenture to ask why the databases were not password secured.
